They are in the silicate group.
Flourite is in a group of minerals known as halides.
Feldspars are classified as silicate minerals.
Neso-, soro-, cyclo-, ino-, phyllo- and tectosilicates are all the groups of silicate minerals.
Quartz is the most abundant single mineral. Feldspars are, as a group, the most abundant minerals. Quartz and feldspars are classified as silicate minerals, the classification of mineral with the most abundance in the Earth's crust.
Important examples of silicate mineral species include forsterite (in the olivine group), almandine (in the garnet group), epidote, schorl (in the tourmaline group), enstatite (in the pyroxene group), actinolite (in the amphibole group), muscovite (in the mica group), albite (in the feldspar group), stilbite (in the zeolite group), and quartz. Important examples of non-silicate mineral species include calcite, gypsum, fluorite, hematite, galena, and gold.
They are classified based on the structure of their silicate group. Silicate minerals all contain silicon and oxygen.
Magnetite is classified as an oxide.
Flourite is in a group of minerals known as halides.
Feldspars are classified as silicate minerals.
Neso-, soro-, cyclo-, ino-, phyllo- and tectosilicates are all the groups of silicate minerals.
Quartz is the most abundant single mineral. Feldspars are, as a group, the most abundant minerals. Quartz and feldspars are classified as silicate minerals, the classification of mineral with the most abundance in the Earth's crust.
Grasshoppers can be classified into the insects group.
Gold is in the gold group. The group is composed of metallic elements that have the same crystal structure as gold. There are only six minerals in the gold group which are gold, silver, copper, mercury, aluminum and lead.
Important examples of silicate mineral species include forsterite (in the olivine group), almandine (in the garnet group), epidote, schorl (in the tourmaline group), enstatite (in the pyroxene group), actinolite (in the amphibole group), muscovite (in the mica group), albite (in the feldspar group), stilbite (in the zeolite group), and quartz. Important examples of non-silicate mineral species include calcite, gypsum, fluorite, hematite, galena, and gold.
Shih Tzu's are classified in the Toy Breed group.
== == Mica is actually a group of silicate minerals, not classified as sedimentary, metamorphic, or igneous, although mica can appear in rocks of all three classifications. == ==
Opals are not truly minerals (because they don't have a crystalline structure), they are in a class called mineraloid. A mineraloid is an amophous, inorganics substance that lacks a crystalline structure, but are mineral in nature. You will find that in many older reference systems, they may well be classed as minerals.
